PICmicro microcontroller family includes low-cost 48 and 64kbyte flash memory devices

Microchip Technology has expanded its PIC18F family of PICmicro flash microcontrollers to include low-cost 48 and 64Kbyte memory devices that offer designers added I/Os, timers, a feature-rich peripheral set and the flexibility of field self-programmability.

Available in 64 and 80-pin TQFP packages, the PIC18- F8525/6525 and PIC18 F8621/6621 microcontrollers are code-compatible with the company's current 18, 28 and 40-pin portfolio. This enables designers to migrate to higher performance devices and to reuse software and hardware in existing platforms, thus lowering overall development costs and enabling a quicker time-to-market.

The microcontrollers feature Microchip's PMOS electrically erasable cell (PEEC) process technology, which provides best-in-class erase/write endurance, retention, and disturb reliability for both program and on-chip data EEPROM memory. Featuring an optimized programming time, an entire memory array can be fully erased and programmed in less than 2s. An individual word can be erased and programmed in less than 3ms.

The devices feature either 48 or 64Kbytes of flash memory, 4Kbytes of RAM memory and 1024bytes of high-endurance EEPROM data memory. The peripheral set includes an ADC with up to 16 channels x 10-bit resolution, 2 Capture/ Compare/PWM modules, 3 Enhanced Capture/Compare /PWM modules, up to 10 MIPS performance at 10MHz, two
8-bit timers, three 16-bit timers and one watch-dog timer (WDT), dual analog comparators and a parallel slave port (PSP).
